Scraper blades are great for moving material from side to side, like pulling gravel from the edges back to a crown and for establishing drainage swales, but a box blade is a better "all-rounder" that does a lot of things well. I use a box blade the most, followed by a land plane grading scraper. Whatever you decide, remember that weight is your friend. 100+ pounds per foot in width is the minimum I would consider.

BOTH i know thats a bad answer but a box just doesn't add the angles and movement that a blade can

I spend more then a few hours on a old Ford Workmaster as a kid with a box grader that was a little to big for it and a regular blade. For fixing gravel roads and pushing back briars and branches the box grader was great but for and dirt work the other blade was the ticket. My gramps and ole man swore by the box but the fact that you could windrow and material could roll off of it made it valuable. I also preferd it for snow cause it was lighter.
